Technical Field

The utility model relates to a vacuum bottle technical field specifically is disposable double-deck vacuum bottle blowing of blow molding.

Background

The existing bottle blowing products can not be made into vacuum bottle products, the existing vacuum bottles can not be made into special-shaped bottle bodies, and no vacuum bottle with both large capacity and special-shaped appearance exists in the market.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a disposable double-deck vacuum bottle blowing of blow molding to solve the problem that provides among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a double-layer vacuum bottle blowing by one-time blow molding is characterized in that a vacuum bottle consists of an outer bottle blank and an inner container blank, the outer bottle blank is sleeved on the surface of the inner container blank, detachable vacuum pump heads are installed at openings of the outer bottle blank and the inner container blank, an interlayer is reserved between the outer bottle blank and the inner container blank, an outer bottle air inlet groove is formed in a thread of the outer bottle blank, an inner bottle air inlet groove is formed in the neck of the inner container blank, the vacuum pump head can inflate and extrude the inner container blank in the interlayer when pressed, and the inner portion of the inner container blank is communicated with a discharge hole of the vacuum pump head.

Compared with the prior art, the beneficial effects of the utility model are that:

1. according to the scheme, the double-layer bottle bodies in various forms can be formed by one-time blow molding after the outer bottle blank and the inner container blank are assembled, the inner container blank is filled with solution after the bottle is blown out, the vacuum pump head is screwed on, the solution is extruded out by the vacuum pump head according to compression deformation because the inner container blank is thin in wall, and the solution filled in the inner container blank is in a vacuum state, so that air in the extrusion process of the vacuum pump head can enter an interlayer between the outer bottle blank and the inner container blank, and the solution in the inner container blank cannot contact with the air to play a role in preservation;

2. the scheme is that the outer bottle blank and the inner container blank are assembled together after being separately molded by injection and subjected to secondary blow molding, and the vacuum bottle has the advantages that the inner container blank can blow out the shape the same as that of the outer bottle blank, the vacuum bottle technology can be realized on large capacity and appearance abnormity through the scheme, the defect of the vacuum bottle on appearance abnormity is filled, and the technical difficulty that the vacuum bottle cannot be realized above the large capacity (200 ml) is solved.

Detailed Description

Example one

Referring to fig. 1-11, the present invention provides a technical solution:

a disposable blow molding double-layer vacuum bottle blowing is shown in figure 1, the vacuum bottle consists of an outer bottle blank 1 and an inner container blank 2, the outer bottle blank 1 is sleeved on the surface of the inner container blank 2, an interlayer 3 is left between the outer bottle blank 1 and the inner container blank 2, and meanwhile, the upper ends of the outer bottle blank 1 and the inner container blank 2 are provided with detachable vacuum pump heads 4;

as shown in fig. 2 and 3, the screw teeth of the outer bottle blank 1 are provided with notches to form an outer bottle air inlet groove 11 for air inlet of a finished product;

as shown in fig. 4 and 5, the neck of the inner container bottle blank 2 is provided with a notch to form an inner bottle air inlet groove 21, which is also used for finished product air inlet;

as shown in fig. 6 and 7, the inner container bottle blank 2 is inserted into the outer bottle blank 1 for assembly, and the assembled bottle blank is placed into a bottle blowing mold for blow molding, as shown in fig. 8, and the wall thickness of the outer bottle blank 1 is firm, and the wall thickness of the inner container bottle blank 2 is thin and easy to compress and deform due to the light gram weight of the inner container bottle blank 2;

and the shape of the bottle mold can be any special shape, so that the vacuum bottle product is blow-molded into a special-shaped bottle shape,

after the finished product is blown, the solution is filled into the inner container bottle blank 2, the vacuum pump head 4 is stored and screwed in vacuum, as shown in figure 1, the inner container bottle blank 2 is thin in wall and easy to compress and deform, gaps are formed in the neck of the inner container bottle blank 2 and the thread of the outer bottle blank 1, the air can enter the interlayer 3, when the vacuum pump head 4 is pressed, the air enters the interlayer 3 from the gaps on the outer bottle blank 1 and the inner container bottle blank 2, the inner container bottle blank 2 is pressed to compress and deform, the solution can be extruded, the solution in the inner container bottle blank 2 can be guaranteed to be in a vacuum state all the time, and therefore the fresh-keeping effect is achieved.

According to the scheme, the outer bottle blank 1 and the inner container blank 2 are assembled and then can be blown into double-layer bottle bodies in various forms at one time, after the bottle is blown out, the solution is filled in the inner container blank 2, the vacuum pump head 4 is screwed on, the solution is extruded out due to the fact that the inner container blank 2 is thin in wall and is compressed and deformed by the vacuum pump head 4, the solution filled in the inner container blank 2 is in a vacuum state, air in the extrusion process of the vacuum pump head 4 can enter the interlayer 3 between the outer bottle blank 1 and the inner container blank 2, and therefore the solution in the inner container blank 2 cannot be contacted with the air, and the fresh-keeping effect is achieved;

and the blow molding bottle can use the principle of the vacuum bottle at present, the scheme is that the bottle blanks are assembled together after being separately molded, and secondary blow molding is carried out, so that the advantage is that the inner container bottle blank 2 can blow out the shape the same as that of the outer bottle blank 1, the vacuum bottle technology can be realized on large capacity and appearance abnormity through the scheme, the defect of the vacuum bottle on appearance abnormity is filled, and the technical difficulty that the vacuum bottle cannot be realized on large capacity (200 ml) is solved.

The product can be widely used in cosmetics, daily chemical products, food, etc.
